Beit known that l1,11 EAN BAPTISTE GUs'rAvE ADOLPHE CANET, engineer, acitizen of lthe Republic of France,` and a resident of Paris, France,have invented certain new and useful Improvements` in and Relating toGun-Mountings, (forrwhichE-Ifh-ave `,obtained a patent in France, No.216,937, dated October 23, 1891,) of which the following is aspecification, reference beingfhadto the accompanying draw-l ings. v

'lhis invention relates to gun mountings. According toene" construction,a sleeve in which the gunslidesis formed on or attached to side framesor cheeks which are provided with trunnions, and in the said sleeve orattached thereto on thelower side thereof is provided a single hydraulicbrake cylinder the piston rod of which is attached to a hoop or. ringfixed on the gun. The said hoop or ring slides onthe said side framesorcheeks duringthe recoil and running out' of the gun. In aslghtlyniodiied form of construction, an additional sleeve through whichthe gun' slides 4 and hascast on it or attached to it a hydraulic isformed on the side frames, and the brake cylinders are arranged at thesides of the gun.

The said invention alsocomprises the p'rovision of subsidiary hydrauliccylinders for running the gun in and out when desired without firing,and also a novel recuperator in combination with the said sleeve, hoopor ring, .and side frames.

In'the accompanying drawings, Figure 1 is a vertical central section ofthe recuperator portion of the gun.

VLike letters denote corresponding parts throughoutthefdrawings.

Referring'to Figs. 1 to 6, A is the gun; B is a-sleeve through which thegun can slide;

ThevsleeyefB is made in one or several parts,

brake cylinder Fbelow the gun. The piston rod F of: this cylinder isattached at its forward extremity by a collar f Figs. 1 and 4 to aprojection E on the hoop or ring E which is suitabiy secured to theexterior surface of the gun'. V,In the construction shown in Figs. 1,'2andg4`the hoop E is secured between projections'Ar formed on the gun anda hoop e constructed in halves and held by means of a ring e2 inarece'ss e' formed in the gun. The projections A constitute aninterrupted collar on the gun. The hoop E is made with parts thatprojectinto and fit in the interruptions of the said collar and thus preventthe gun from turning in the hoop during the recoil. The said ring may beotherwise secured to the gun, for example, it may be placed while hotupon the gun and shrunk into its place thereon. l

The side `frames C, C serve as slides along which the hoop E, whichissuitably recessed or grooved at ei'c Fig. 4 for the purpose, moves inits recoiland return. These side frames may or may not be braced bysuitable trunnions and may be provided' at the rear with stops orbuffers to diminish the shock of recoil. A stop C2 is fixed in theforward end IOO ward'rnovement of the gun.

The hydraulic brake employed in this mounting, is furnished with a,taper rod F2 arranged to enter acentral aperture F3 in the piston forthe purpose of regulating in a well lnown manner the area of the openingthrough which the liquid, displaced by the entranceinto the cylinder ofthe piston rod F', flows fromone to the other side of the piston duringthe recoil. The liquid so displaced operates to force outward the loosehead F4 of the brake cylinder yand thereby compresses a springrecuperator which serves to run out the gun at the end of 'the recoil.The recuperator consists of springs G G G G', threaded upon rodsH. Thesprings-G G bear at their rear ends against the front of the head F4 andat' their Aforward ends vagainst nuts H screwed on the rods H. Thesprings G G bear at their-forward ends against a flange F5 of the brakecylinder and at their rear ends against shoulders i12-formed on the rodsH. H3 is a piece secured to the brake cylinder and forming a guide forthe rear ends of the rods H. A

A spring loaded valve F6 which is mounted on the piston rod in front ofthe piston is raised from its seat by the pressure of the liquid flowingthrough orifices F7 F7 from one to the other side of the piston duringthe recoil, and returns to its seat when the recoil is finished thuspreventing the return of the liquid and maintaining the gun run in untila return thoroughfare is opened. This valve is in some cases perforatedwith small bypass orifices f6 which allow-of the slow return of eachfside frame or beam to limit the `forof the liquid and thus permit of theimmedi ate commencement of the running out of the gun under the actionof the recuperator while however moderating the' speed of the runningout.

F8 Fig. l is a passage formed in the wall of the brake cylinder andcommunicating with the ends of the said cylinder on opposite sides ofthe piston. The area of lopening of this passage can be regulated or thesaid passage can be closed entirely by means of an adjustable valvecomposed of a conical screw plug F" which is adapted to be screwed downupon a seat formed in the metal around the passage. By means of theadjustable screw-valve controlling the passage or thorough fare FS thespeed of running out can be regulated at will. Orilicesffare madeleading into the said passage F8 on opposite sides of the screwdownvalve F into which orifices can be inserted the delivery pipe of a pumpin case it should be necessary or desirable to use the same for runningthe gun in and out of battery. When a pumpis not in use for the purposethe said orifices are closed by screw plugs fzfz. The action of thebrake cylinder is well understood and need not be further explainedhere.

The mounting illustrated in Figs. 7 to l2 possesses the same generalcharacteristics as those above described, that is to say, it comprisesthe rear sleeve B to which are attached the side frames, beams, orchecks C, C but there is a difference in respect of the arrangement ofthe brake cylinders F of which according to this part of the inventionthere are two placed one on each side of the sleeve B. n this mountingis also provided a forward sleeve B infront of the fixed hoop or ring E.The trunnions are formed on the sleeve B and project through and fitinto openings C3 provided in the side frames C. The sleeve B is fittedwith bushes B2 B2 which can be re- 'meved when Worn and replaced by newones. The side frames C are made with central openings which form guidesfor the hoop or ring E that is constructed to slide therein during therecoil and running out of the gun.

The construction of the brake cylinders is case the excess of liquidexpelled by the entrance of the piston rods into the brake cylinders,passes out through pipes F10 which communicate with a valve box Jcontaining a spring loaded non-return valve E6 and raises said outletvalve and passes along a pipe c to a reservoir of compressed gas or airK Fig. 13 or into an air recuperatorunder spring pressure. The said airor gas recuperator is constructed of one or more hollow cylinders Kconnected to each other at both ends bypipes K2, K3 and provided withpistons K4 above which is the air or gas under pressure. The y liquidenters the recuperator at the lower end below the said pistons which arecovered by a slight depth of liquid. rlhis arrangement effectively'prevents the escape of the air or gas under pressure in the recuperator.

A passage Jf Fig. 8 fitted with a plug vor screwdown stopper J2 isprovided to permit the liquid to reenter the brake cylinders and forcethe gun back into battery when required.

A special device is shown in Figs. 8 and l0 which allows the gun to bemoved into and out of battery at will. This device comprises two or morehydraulic cylinders L mounted or formed on the sleeve B and providedwith pistons L the rods L2 of which are normally or under ordinaryconditions locked by pins L3 passing through the same and through apiece L4 fixed to the cylinder. The forward end Lof each piston rod isadapted to be coupled by a pin for example to a stud LG or the likefixed in the hoop or ring E. For running the gun in, it will besufficient to disengage the pins L3, move the piston rods L2 forward,connect the said rods to the studs L6 and then inject liquid underpressure in front of thev pistons L of Vsaid hydraulic cylinders. Themounting shown in Figs. 14 to 17 is also characterized by substantiallythe same features in respect of the rear sleeve and the side frames orcheeks furnished with trunnions. The said frames or cheeks however inthis modification are united at their forward ends by a piece B cast onor otherwise attached thereto and forming with a cover or cap ll3 asleeve similar to that above described, but in this' IDO IIO
